Help me with algebra, its super important? ?

Two ships are sailing in the fog and are being monitored by tracing equipment. As they come into the observer's rectangular radar screen, one ship, the Rusty Tu, is at a point 900 mm to the right of the bottom left corner of the radar screen along the lower edge. The other ship, the Bucket of Bolts, is located at a point 100 mm above the lower left corner of that screen. One minute later, both ships' positions have changed. The rusty Tube has moved to a position on the screen 3 mm left and 2 mm above its previous position on the radar screen. Meanwhile, the Bucket of Bolts has moved to a position 4 mm right and 1 mm above its previous location on that screen.



Assume that both ships continue to move at a constant speed on their respective linear courses. Using graphs and equations find out if the two ship will collide.



How do i graph it on the computer? what do i need?!?!

how do i use excel? its so confusing



HELP ME PLEASE

ive got one hour to get it, graph it, andd finish it! =[



i have good old traditional graph paper, so hwo do i graph it?Help me with algebra, its super important? ?
Just graph this on paper to start. The lower left corner of the radar scope is the same as the (0,0) point on the graph paper. Use the squares to set up axis values, such as one square equals 2 mm. The issue is to figure out what the velocity vectors are so that you can determine if the ships will achieve the same point in space at the same moment of time. Plot the two points each ship has, so for instance the first ship has the two points (900,0) and the second point is (897,2) and the second ship has the points (0,100) and (4, 102). Remember that time is an issue here. Just drawing the two lines and seeing that they intersect is not good enough. You need to find what that intersection point is and see when each ship will be there. They will only collide, after all, if they get there at the same time. You know how many mm each ship moved in 1 minute so just calculate how many minutes it will take each ship to get to that point.Help me with algebra, its super important? ?
step 1: calm down

step 2:make a scaled down drawing:

picture the rectangular radar screen, and the two dots representing the ships in the first part. then make more dots for their new positions, and draw a line showing their paths.

step 3: the ships are going in straight lines, and at constant speeds, so work out how fast they were going and how far they travelled in that one minute. use speed=distance/time

step 4: you should now have enough information to work out if they will collide or if they will miss eachother.



good luck
Graph paper.

Plot their original points, make each square on the graph represent 1 mm.

Now plot the point they have moved to.

The the ruler and draw a line from where each ship was to where it is now, but continue the line on in that direction until you see the two ships either collide or pass each other.
You'd have to choose a scale, say, one graph block = 50 mm.

You only need the first quadrant of the graph, positive x and y.

The bottom left would be (0,0). One boat starts at (0,100) and goes up 1 for every 4 over to the right, so up 100 and over 400 from the starting point put another dot (it will be at (400,200) and draw a line. The other boat starts at (900,0) and goes up 2 and over to the left 3 so up 200 and left 300 from the start put a dot (at (600,200) and draw the line. The paths will intersect but you need to see if both boats will reach the intersection point at the same time or not.
